New: Progress bar added to MComboBox.

RevBy: Daniel d'Andrada
Details:
Now, for long taking selections, MComboBox can display progress indicator.
I've added ProgressIndicatorVisible property to MComboBox and helper functions:
showProgressIndicator, hideProgressIndicator

My changes also required to update MContentItem, so I moved
additionalItem to MContentItemModel class, and changed MContentItemView
to update layout when additionalItem property is changed.

WidgetsGallery comboboxpage updated to show new feature of MComboBox.
